Which would sound better in sealed with 1114rms?

2 12" Dayton HO's or 2 12" Sundown Audio SA12.

Box is 1.1cf sealed, each chamber.
Amp is JBL GTO1201.1. (1114rms @ 2ohms)
Car is a Camaro hatchback.
Interior speakers are MB Quart coaxils, powered off the factory Delco amp. They get loud, but mid-bass is sloppy. I plan on upgrading to something better with their own aftermarket amp later down the road.

Looking for the cleanest sound possible, but loud.

And I was told by the person @ parts-express.com that the Daytons come in 4ohm SVC, so I can wire the coils parallel to get 2ohms. But, I couldn't find the SVC Daytons on the site, just DVC. Is he bullshittin'? Can someone point them out to me?
